3D Printing Filament Tools
Free calculators for 3D printing. Unlike generic tools, our price checkers compare your numbers against SpoolIndex's live cross-store filament pricing, so you know whether a deal is actually good right now.
Filament Cost Calculator
Estimate the filament cost of a print from grams used and price per kg or spool.
Filament Price-per-kg Checker
Convert a spool price to $/kg and see how it compares against current live offers.
Filament Weight & Length Converter
Convert filament grams to meters (and back), with optional cost, by material and diameter.
Looking for the best price instead of a calculator? Browse the live filament deals ranked by value per gram, or compare brands on the comparison pages.
